Abstract: Abstract of the Disclosure Containers formed of a flexible sheet of material capable of being sealed for closing off the interior of the container from the ambient atmosphere.  The sheet material is resistant to tearing and includes an inner surface and an outer surface.  The container comprises a mouth portion including a peel strip or layer fixedly secured to the inner surface of the material and extending substantially the entire length of the mouth portion, with adjacent portions of the peel strip or layer being in releaseable engagement with each other.  The engagement forms an air-tight interfacial seal at the mouth which is readily openable by peeling the engaging portions of the peel strip or layer from each other to provide ready access to the interior of the container without tearing the sheet material forming the container.  Thus, the container can be readily reclosed by conventional mechanical means, such as folding, tin ties, etc.        Some containers are formed in accordance with the method for applying the peel strips transversely across a web sheet material and heat sealing the strips to the material at longitudinally spaced locations and thereafter severing the web into sections which are formed into the container.  Other containers are formed by use of a peel layer on the entire inner surface of the container.  The peelable interfacial seal for such containers is formed by heat sealing the same within a desired temperature range.  The remaining seams of the container are permanent and are formed by heat sealing the same at temperatures in excess of those used in making the peelable seal.

Abstract: ABSTRACT         Fluid is applied under pressure to the inlet  port (60)  of  a  valve   assembly   (10)  associated  with  an inflatable   packer.      When   the  pressure  reaches  a predetermined level the force acting on first piston  (20) and transmitted through second  piston (30), closing shear pin  (74)  and  stem  (40)  is sufficient to break opening shear pin (73) thereby permitting the first  piston  (20), second piston (30) and stem  (40)  to move to the right as shown  in  Figure  1a.  A locking ring (41) expands into a cavity (51) in  annular  gland  (50)  thereby  restricting further movement of the  stem  (40).   Fluid flows through inlet  port  (60)  and  outlet port (61) to the inflatable packer.  A line  connects  the  inflatable  packer  to  an overpressure  port  (62).     When  the  pressure  at  the overpressure  port  (62) reaches a predetermined level the closing shear pin (74) breaks and the second  piston  (30) moves to  the  left,  engages  the  first  piston (20) and pushes  it to the left to prevent further fluid flowing to the  inflatable  packer  and  completely   isolating   the contents of the annulus (2)  from the inside of the casing if  the  inflatable  packer ruptures.  A locking ring (75) ensures  that  the  first  piston  (20)  cannot  move   to re-establish fluid  communication  between  the inlet port (60)  and  the outlet port (61) once the first piston (20) has returned to its initial position.

Abstract: Abstract Film Cooling Slot With Metered Flow The wall of a hollow airfoil for a gas turbine engine includes a film cooling slot therein elongated in the longitudinal direction and having a base within the wall and an outlet at the external surface of the airfoil.  A plurality of metering passages extend from inlets at the internal surface of the wall and intersect the slot near its base. The metering passages are angled to direct a metered flow of coolant fluid at a sharp angle against a surface of the slot to cause turbulence and diffusion of the coolant fluid within the slot in order that the coolant fluid fill the entire slot. The coolant fluid thereupon exits the slot as a thin film over the surface of the airfoil downstream of the slot outlet along the full length of the slot.

Abstract: ABSTRACT     A cassette cleaner adapted to be positioned in a cassette receiving recess of a video player/recorder.  A cleaning ribbon is mounted in the cassette cleaner, and guide members of the video player/recorder carry the cleaning ribbon outwardly into cleaning engagement with the rotating head of the player/recorder.  The cassette cleaner has a stationary locating element which restrains outward movement of a portion of the ribbon so that the ribbon engages the peripheral surface of the rotating drum that carries the head member along two contact locations of relatively short arcuate length.  This reduces the frictional engagement of the ribbon relative to the rotating drum.

Abstract: ABSTRACT             A diversity receiving system for differential detection of minimum shift key (MSK) signals.  The system may by advantageously implemented in order to realize high quality mobile satellite communication systems where shadowing is a significant problem and channel bandwidth and power are constrained.  Signals from each of a plurality of receiving branches are translated to different intermediate frequencies which differ from each other by multiples of the transmitted signal symbol rate. The intermediate frequency signals are summed and detected via a common differential detector, the latter being followed by a low pass filter having a bandwidth corresponding to a fraction of the symbol rate.  The plural signals are easily and stablely combined at an intermediate frequency stage without phase adjusters, signal quality measurement circuits or switching controllers. Moreover, the error rate performance is equivalent to that of post detection equal gain combining diversity schemes, which require plural complete receiving systems.

Abstract: MICROWAVE APPARATUS             ABSTRACT OF THE DISCLOSURE      In  order  to  supply  a  d.c.  bias  to  the  drain electrodes of MESFETS (1-4)  in a distributed amplifier operating in the 500MHz to 20GHz or above, a d.c. source (15)  is connected to the drain line  (5,9,11,14) via a feed component (16) which comprises a ferrite bead (17) having an axial aperture (18).  A coil (19) comprising, for example, four turns of 20 micron gold wire is wound on the bead in toroidal fashion.  The bead may be of the kind  which  is used  for  low-frequency  interference suppression or for encircling the emitter lead-out wire of a bipolar transistor operating in the lower megahertz range.  At  these  relatively  low  frequencies  in  the conventional use of  the bead,  the bead material will exhibit  low  magnetic  losses  and  high  permeability.          However, in the present invention, due to the microwave signal in the coil, the bead operates over a frequency band which is many times higher than its normal operating band.   At  these  high  frequencies  the  bead  material exhibits quite large losses.  The feed component acts, as far as the microwave signal is concerned, as though it is a  relatively  large  resistor,  which  isolates  the  low impedance of the d.c.  source from the microwave signal path in the drain line.  As far as the bias supply is concerned, the d.c. resistance of the coil is negligible, so that there is virtually no d.c. power dissipated in the feed component.  The feed component can be used for other applications where a high resistance at microwave frequencies is required, together with substantially zero d.c. resistance.
